Scientists Uncover Evolutionary Past of Hallucinogenic 'Magic' Mushrooms - 0 views
-
This new study, though, places the two separate groups into different families: the Psilocybe (family Hymenogastraceae) and the Deconica (family Strophariaceae s.str).
-
It's likely that the mushrooms evolved independently instead of possessing a common ancestor. Another option is that they underwent several evolutionary losses, probably for ecological reasons.

Sulfur finding may hold key to Gaia theory of Earth as living organism - 0 views
-
One of the early predictions of this hypothesis was that there should be a sulfur compound made by organisms in the oceans that was stable enough against oxidation in water to allow its transfer to the air.
-
"Dimethylsulfide emissions play a role in climate regulation through transformation to aerosols that are thought to influence the Earth's radiation balance,"
-
measurements revealed an unexpected variability in an isotopic signal that appears to be related to the way the sulfur is metabolized

The computer turns the yeast on by flashing a red light, and it turns the yeast off by flashing a deeper red light. Connected to the yeast is a “reporter” molecule that fluoresces when the protein is produced. The computer can see this fluorescence and alter the light it emits, thus creating a full feedback loop.

computers could ultimately control a multitude of biological processes

The Secret of the Fibonacci Sequence in Trees - 1 views
-
"I compared my results on graphs, and they were interesting! The Fibonacci tree design performed better than the flat-panel model. The tree design made 20% more electricity and collected 2 1/2 more hours of sunlight during the day. But the most interesting results were in December, when the Sun was at its lowest point in the sky. The tree design made 50% more electricity, and the collection time of sunlight was up to 50% longer!"

cells in sharpshooters that were jam-packed with bacteria, which converted the raw materials from sap into the vitamins and amino acids the insects need to survive
-
The glassy-winged sharpshooter has two different resident bacteria, each of which creates different nutrients for the host insect from its base diet of plant sap.
-
The bacteria, in turn, have very limited genomes. They wouldn’t be able to survive without the host insects to provide protection and a ready supply of food.

Observations: Plants cannot 'think and remember,' but there's nothing stupid about them... - 0 views
-
"Biology teachers, researchers, students and lay people all make the same mistake. I'd much rather say a plant senses and responds, rather than the plant 'knows.' Using words like 'intelligence' or 'think' for plants is just wrong
-
saying that because the surface of a pond continues to ripple once struck by a pebble, the water is "remembering" something. The analogy doesn't quite hold.
-
When exposed to strong light, Karpinski explains, plants absorb more energy than they can use for photosynthesis—but he doesn't think plants waste this excess energy. Karpinski says plants convert the energy to heat and electrochemical activity that can later trigger biological processes, like immune defenses.
